5 * This file has test cases to test the sendto () call
6 * for 1-1 style sockets
7 *
8 * TEST1: Sending data from client socket to server socket
9 * TEST2: Sending data from accept (server) socket to client socket
10 * TEST3: Sending data from unconnected client socket to server
11 * TEST4: sending partial data from a buffer
